The conflict centers on Lady's black-and-white view of demons as evil and humans as good, while the White Rabbit's experience shows that demons can be kind and humans can be cruel. This ideological clash is deepened by their shared past and the tragic events that separate them, making their confrontation a reflection of misunderstanding and trauma rather than simple good versus evil.

Episode 6 delves into Lady's past, revealing her childhood trauma and the origins of her hatred toward demons. It shows her relationship with her oldest friend, who becomes the White Rabbit, and how their differing views on demons and humans shaped her path as a demon hunter. This backstory adds emotional weight and complexity to her character.

The episode uses alternating art styles to represent the vastly different subjective experiences of Lady and the White Rabbit. Lady's story is depicted with a more realistic style reflecting her traumatic but grounded life, while the White Rabbit's perspective is shown in a more dream-like, childish animation style. This visual contrast helps the audience understand their conflicting worldviews.

The sudden appearance of a giant demon attacking everyone acts as an external force that prevents Lady and the White Rabbit from reaching an understanding. It triggers violent conflict and forces Lady to take drastic action, including using a bomb that kills most demon migrants, escalating the tragedy and reinforcing the episode's themes of misunderstanding and violence.

While it can be enjoyed as a standalone episode, 'The First Circle' deepens the series' exploration of moral ambiguity, trauma, and the blurred lines between good and evil. It respects the audience's intelligence by allowing interpretation rather than explicit exposition, emphasizing emotional storytelling through visuals and minimal dialogue. The episode highlights the complexity of characters and the social relevance of prejudice and conflict.
